Mark global with hidden attribute

GCC 5 will generate a relocation for protected symbol:

https://gcc.gnu.org/bugzilla/show_bug.cgi?id=65248

when compiling for a shared library.  It is undefined to access protected
symbol in IFUNC selector function inside a shared library.

	PR gold/18628
	* testsuite/ifuncdep2.c (global): Change protected to hidden.
	* testsuite/ifuncmod1.c (global): Likewise.
	* testsuite/ifuncmod5.c (global): Likewise.
